I'll add that the one doe that I did shoot with a core-lokt, the little 100 grain 6mm pill entered as tight behind the shoulder as physically possible and she dropped. problem is, it didn't exit, and the hole looked like a scalpel incision about a quarter of an in wide. I looked at her, and flipped her over, couldn't find it. Seemed like a textbook heart/lung shot with the blood dripping from her nose, then I flipped her over again and put pressure on her chest and was squirted in the face with blood. 2 ribs were destroyed and the vitals were jelly. Seems like a good thing I made a perfect shot, if she had run I doubt I'd have found much of anything.
